Overview
The OPA340MDBVTEP is a single-supply, rail-to-rail operational amplifier produced by Texas Instruments. It is optimized for low-voltage, single-supply operation and is well-suited for a wide range of general-purpose applications. The OPA340 features rail-to-rail input and output, high-speed operation, and low power consumption, making it ideal for driving sampling analog-to-digital (A/D) converters, audio applications, and providing current/voltage conversion at the output of digital-to-analog (D/A) converters. The device operates on a single supply as low as 2.7 V and is available in SOT23-5 and SOIC-8 packages, specified from –55°C to 125°C.
